An Introduction to Functions Chapter 4 Review

Front

What is a function rule?

Back

A function rule is a mathematical expression that describes the relationship between input and output values in a function.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be represented by a straight line on a graph, meaning it has a constant rate of change.

Front

What is an independent variable?

Back

An independent variable is the input value of a function, often represented as 'x'.

Front

What is a dependent variable?

Back

A dependent variable is the output value of a function, often represented as 'y', which depends on the independent variable.

Front

How do you determine if a function is linear or nonlinear?

Back

You can determine if a function is linear or nonlinear by examining the rate of change; if the rate is constant, it is linear.

Front

What is a function table?

Back

A function table is a chart that shows pairs of input and output values for a function.

Front

What is the slope of a linear function?

Back

The slope of a linear function represents the rate of change of the function, calculated as the change in y over the change in x.

Front

What is a function graph?

Back

A function graph is a visual representation of the relationship between the input and output values of a function.
